Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...
Frequency spread spectrum (FSS) is a technique that’s been widely used in power-conversion designs to reduce electromagnetic-interference (EMI) noise. But optimizing EMI without compromising on other ...
